Top LLM app developers, active now
LLM app developers turn large language models into products people use every day: a support assistant on your website, a tool that drafts quotes from a spec, or an internal search over contracts and policies. The hard part is rarely the model. It’s the data, the user interface and making answers dependable.
Look for someone who has shipped to real users, can explain how they test answer quality and has a plan for costs, privacy and what happens when the model gets it wrong.

Questions
LLM apps: common questions
When does a small business need an LLM app developer?
When an off-the-shelf chatbot can’t see your data or fit your process. Common starting points are answering customer questions from your own help content, drafting documents from templates and pulling structured details out of emails, forms or PDFs.
What should I ask before hiring?
Ask to see something they’ve shipped and how they measured whether it worked. Ask where your data will be sent and stored, what it will cost to run each month, and how your own team will maintain it once they’ve gone.
How long does a first project usually take?
A focused proof of concept on your own data often takes two to six weeks. Getting it robust enough for customers, with logging, guardrails and testing, usually takes as long again. Be wary of anyone who promises production quality in a few days.
